<h3>
Answer: C. a balance and a beaker</h3>
Explanation:
A balance would be used to measure the weight, which in turn effectively measures the mass (more or less). Imagine that we have a brick that we know is 1 pound. If we have an object that needs 5 bricks on one side to balance it out, then we know the object is 5 pounds.
The beaker is used to measure the volume. It's basically a measuring cup that you would find in the kitchen.
To get the density, you divide the mass over volume.
For example, if you have a material that has a mass of 100 grams and it's volume is 20 cm^3, then its density is 100/20 = 5 grams per cm^3.
The mix of alleles from various genes that end up in the daughter cells is determined by the anaphase 1 of meiosis 1.
Chromosome segregation during meiosis is mirrored in the segregation of alleles. During anaphase, 1 of meiosis 1 homologous chromosomal separation leads to allele segregation.
Chromosomes display autonomous assortment when they are randomly split into daughter cells during meiosis.
<h3>What takes place in anaphase 1?</h3>
During meiosis I, sister chromatids remain together as homologous chromosomes separate. To appreciate the development of germ cells, it is crucial to comprehend how this odd chromosomal segregation behavior came to be. Here, we show that the pattern of chromosomal segregation during meiosis I is determined by the microtubule-kinetochore interactions that are inhibited during prophase I and the premeiotic S phase.

Answer:
New allele combinations are acted upon by natural selection.
Explanation:
Recombination may be defined as the process of the exchange of the genetic material between the homologous chromosomes of the non sister chromatid. The combined trait will be visible in the upcoming generation.
The recombination allows the generation of the new genes in the population. These new genes if beneficial for the population will be pass to the next generations. The new allele will be favored by the natural selection and increases the chance of survival of the population.
Thus, the correct answer is new allele combinations are acted upon by natural selection.

The main difference between Archaebacteria and Eubacteria is? Hint: Archaebacteria are called ancient bacteria whereas eubacteria are called true bacteria. Unlike eubacteria, archaebacteria can survive in extreme conditions
